Pong, basically. With the addition that the ball's speed increases with each collision, making it get pretty tense. First to a score of 10 wins. 😊
This game was made for trollsplatterer.be, where you'll find the *.gmk example. The game uses only one script (that includes no sprites, step event, etc). Though for releasing here it does use Yourself's hi-res timer DLL, it is kind of needed for this kind of thing (the editable doesn't use it though, just to avoid confusion).
